Biosolids

The two key documents covering the management of biosolids for wastewater managers and transporters are:

The Guidelines outline the requirements for biosolids reuse, including  sampling and analysis to classify biosolids as well as management measures for acceptable reuse. 

The AMM is a companion document to the Guidelines and provides the minimum legal requirements for the classification and reuse of biosolids in Tasmania (Local Government may also require a development application and impose conditions on some biosoids reuse activities). 

Information Bulletin 105 Classification of Contaminated Soils (IB105) may also be relevant to the management of soil-like (non-liquid) biosolids when they contain elevated levels of contaminants.  For instance, IB105 may provide guidance in determining management and / or disposal of biosolids in the following scenarios:

  • if  the Guidelines classify the biosolid as Grade C for contaminant grade; or
  • if a contaminant not listed in the Guidelines is likely to be present at elevated levels in the biosolid.

The Sewage Sludge Management Plan Guidelines, September 2014 offers guidance on information that must be provided to the EPA to satisfy the Sewage Sludge Management Plan conditions set down in a Permit or Environment Protection Notice (EPN).‚Äč 

The EPA Division is a member of the Australian New Zealand Biosolids Partnership (ANZBP) whose role is to support the sustainable management of biosolids in Australia and New Zealand.  This group is managed by the Australian Water Association and includes biosolids producers, processors, transporters, users, regulators and research institutions.  The public area of the ANZBP website contains useful information on biosolids.
